Description

Overview

The BPW ABS ring provides the 80-tooth rotating reference required by the wheel-speed sensor on compatible trailer hubs. Its clipped mounting profile suits specific BPW K and N axle arrangements where the ring must seat firmly and run concentrically with the hub.

Features

• 80-tooth ABS exciter ring
• 180mm maximum outside diameter
• 150mm minimum inside diameter
• Clipped mounting design

Specifications and Materials

The stepped ring profile measures 150mm, 174mm, 176mm and 180mm across its different locating surfaces, with an overall height of 19.5mm. Match every locating diameter rather than relying only on the largest outside measurement.

Part number: 070.417.

See the BPW trailer axle spare parts guide

Compatibility and Fitment

Confirm the 80-tooth count, clipped attachment, stepped diameters and existing hub reference before fitting. A 100-tooth ring is available with the same main diameter profile, so tooth count is the most likely ordering mistake for this application.

Compliance and Safety

Clean the hub locating surfaces and press the ring into position evenly without bending its stepped profile or damaging the teeth. After installation, rotate the hub and confirm consistent sensor clearance, secure retention and no contact between the ring and sensor.

Trailer Applications
